New method for updating failure rates and proof test intervals of equipment groups within safety instrumented systems
Safety instrumented systems (SIS) are to be followed up during operation at a facility. An important part of SIS follow-up is to ensure that all relevant SIS requirements from the design phase are fulfilled during the entire lifetime of the facility. The safety integrity level (SIL) and the...
Standardised Failure Reporting and Classification of Failures of Safety Instrumented Systems
Safety instrumented systems (SISs) implemented on petroleum installations must be highly reliable to protect human life and environment. As of today, monitoring and follow-up of technical status of SIS components require considerable manual effort by extracting and interpreting maintenance and...
Guideline, Standardised failure reporting and classification of Safety Instrumented Systems (SIS) failures in the petroleum industry
Operational data-driven prediction for failure rates of equipment in safety instrumented systems: A case study from the oil and gas industry
Failure rates of safety critical equipment based on inventory attributes
Reliable failure rate estimates of safety critical equipment is crucial for verifying performance requirements and for trending the safety performance of the equipment. Joint industry efforts, like OREDA, Exida and PDS handbooks, supported by international standardization on data collection such...
Common cause failures in safety-instrumented systems: Using field experience from the petroleum industry
Safety instrumented systems often employ redundancy to enhance reliability, but the intended effect may be reduced when common cause failures are taken into account. It is often assumed that a certain fraction of component failures will occur close in time, due to a shared cause. Unfortunately, few...

Barriers to prevent and limit acute releases to sea. Environmental barrier indicators.
This report summarizes the work performed in PDS-BIP activity 2: "Environmental barrier indicators". The purpose of the present report is to propose a set of suitable indicators for a specified drilling scenario and to describe a methodology for developing such indicators. Oppdragsgiver...
